I am an Associate Professor  in Software Engineering in the Department of Computer Science at the University of Oxford. I obtained my PhD (2008) and BSc (1st Class Hons. 2004) from the University of Cape Town, South Africa.

My current research revolves around low power sensing, localization and signal processing in wireless sensor networks and embedded systems. I am driven by solving real world problems. In particular, I am working on developing magneto-induction (MI) as a key technology for communication and localization in areas where wireless and GPS fail, such as underground or indoors.

I originally developed MI localization to tackle the real problem of monitoring where burrowing animals are when they are underground. Key to this was the development of a novel tracking system (essentially underground GPS) that can localize badgers in 3-D with a precision of 30cm. This was published in SenSys 2010, winning the best presentation award.

Previously,  I worked as a postdoc on the WildSensing project, which monitored 70 badgers and their environment over the period of a year using a hybrid RFID/Sensor Network approach. During this time, I also developed a technique for automatically evolving sensor network control systems to achieve a particular task (such as target tracking). This was inspired by the way cells act as a distributed control system through protein signalling and gene regulation.

October 2013: I have been appointed as a University Lecturer (Associate Professor) in the Department of Computer Science, University of Oxford

June 2012: Our novel tracking technology has been featured in Wired:

In 2011 two young Oxford academics came up with a potentially game-changing positioning technology developed from tracking badgers in Wytham Woods, just outside Oxford. Nine months on, Andrew Markham and Niki Trigoni — along with CEO Jean-Paul van de Ven — are in “the early stages” of trying to raise £1.2 million for their spinout, OneTriax. They are ready to go public with a technology that they believe is so far ahead of the game as to have “no competitors”…[read more]
